Results from Linaro’s test farm.
Regressions detected on arm and arm64 (Juno-r2)

perf test cases failed
  perf:
    * perf_record_test
    * perf_report_test
    * Track-with-sched_switch (ignore intermittent failure)

Bad case:
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.002 MB perf-lava-test.data ]

when it was pass it prints number of samples like below,
Good case:
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.004 MB perf-lava-test.data (46 samples) ]

steps to reproduce:
# perf record -e cycles -o perf-lava-test.data ls -a  2>&1 | tee perf-record.log
